I would like to ask about the payload. When I did the "make menuconfig" it wasn't by default the SeaBios., there wasn't at all ...there was GRUB 2 and I selected it...so My question is would it work as SeaBios to boot from usb ?
No.
SeaBIOS is a BIOS implementation and BIOS is fortunately x86-specific.
The method used by BIOSes to boot from USB doesn't apply at all on other machines.
Unless someone provides a well-tested recipe for creating a full working solution to replace what was shipped on your device I would very strongly discourage you from experimenting with firmware unless you are prepared to spend many days on doing recovery and years on learning, as well as maybe a hundred USD/EUR/GBP on tools.
